Alright. So ... I'm trying to understand the gain of using Bio(3). I'm not seeing it yet, but I'm willing to be educated. Would you want to import tcs(1) as well?
Bio's formatted I/O routines are fully utf-8 aware. E.g. when looking to
consume or output a character they know how many octets are required to form
any given unicode character. The upside is you never have to think at all
about processing utf-8 -- it just happens.
Another benefit is that print() and friends let you install custom formatting
verbs. So you can do things like:
int to_qp(Fmt *fmt) {/* convert data to quoted-printable */};
fmtinstall('Q', to_qp);
and then
char *text = "some string with non-ascii text";
print("%Q\n", text)
and the %Q conversion formats its output as quoted-printable on the fly.
Similarly, you could define verbs that know how to encode stuff in headers,
escape and quote addresses as necessary, etc. In some situations this can
really help improve the code's readability.
